СИСТЕМА МЕХАНИЧЕСКОЙ ТРАНСМИССИИ "MULTIMODE" Multi-Mode Manual Transmission Warning Light Circuit

DESCRIPTION

The combination meter interprets the multi-mode manual transaxle system condition according to the information from the INDC and INDA circuits, and if necessary, illuminates (blinks) the multi-mode manual transaxle warning light and sounds the buzzer.


The contents of signals from the INDC and INDA circuits, and the status of the multi-mode manual transaxle warning light, buzzer and indicator are shown in the table below.

Tech Tips

Check that the multi-mode manual transaxle warning light and shift position indicator light come on.

Under normal conditions, the shift position indicator indicates the current gear position when the ignition switch is turned ON, and the multi-mode manual transaxle warning light comes on for bulb check for approximately 5 seconds when the ignition switch is turned from off to ON.

If the shift position indicator light does not come on, the INDA circuit may be malfunctioning. If the multi-mode manual transaxle warning light does not come on, the INDA and/or INDC circuits may be malfunctioning.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TCM - COMBINATION METER ASSEMBLY)


    1. Disconnect the TCM connector.

    2. Disconnect the combination meter assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      E104-29 (INDC) - E46-22 (BRQ) Always Below 1 Ω
      E104-31 (INDA) - E46-23 (TX+) Always Below 1 Ω
      E104-29 (INDC) - Body ground Always 10 kΩ or higher
      E104-31 (INDA) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG
    OK
  2. INSPECT COMBINATION METER ASSEMBLY

      Tester Connection Condition Specified Condition
      E46-23 (TX+) - Body ground Always 3.64 V or higher
      E46-22 (BRQ) - Body ground Always 3.64 V or higher
      Result
      Proceed to
      OK
      NG
